The presence of the neuropeptide C-terminal flanking peptide of neuropeptide-Y, C-PON, has been investigated in the main olfactory bulb of the rat using conventional fluorescence and peroxidase-antiperoxidase immunocytochemical techniques. The distribution of immunoreactive structures to C-PON was examined in both horizontal and coronal sections. Endogenous C-PON was localized within two types of short-axon cells including (1) superficial short-axon cells in the glomerular layer and (2) deep short-axon cells lying in the deepest portion of the granule cell layer and in the adjacent white matter. In addition, varicose immunoreactive processes were detected in all layers, although they were more numerous in the deepest portion of the granule cell layer. Immunoreactive cell bodies and processes were also observed in the nucleus olfactorius anterior and in the intrabulbar portion of the anterior commissure. Nevertheless, immunoreactive structures were not localized in the lateral olfactory tract. The indirect immunofluorescence technique to detect endogenous C-PON in combination with the enzyme histochemical demonstration of NADPH-diaphorase activity, in single sections, showed that the NADPH-diaphorase procedure is a reliable marker for these C-PON positive cells. Also, indirectly, that, in the rat main olfactory bulb, C-PON and neuropeptide-Y are contained in the same cell types. Many glomeruli were stained following the NADPH-diaphorase procedure, but they were not C-PON immunoreactives. Results of this study provide evidence suggesting that C-PON may influence polysynaptically the function of mitral cells and, therefore, the olfactory bulb output.

The indirect immunofluorescence technique to detect endogenous C-flanking peptide of neuropeptide Y (NPY), C-PON, in combination with NADPH-diaphorase (NADPH-d) histochemistry, were applied to the same sections to establish whether C-PON containing cell bodies in the rat striatum can be labelled by their content of NADPH-diaphorase activity. NADPH-diaphorase activity proved to be a reliable marker for these positive C-PON neurons. Our results suggest that, in the rat striatum, C-PON, SOM and NPY co-exist in the same cells.
